Title:
FLEXIBLE DISPLAY PANEL AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/077498
Kind Code:
A1
Abstract:
A flexible display panel; a non-display region of the flexible display panel is provided with a bending section (203), the bending section (203) comprising a flexible substrate (204), an insulating layer (205) that is provided on the flexible substrate (204), a metal wiring layer (206) that is provided on the insulating layer (205), and a flat layer (207) that covers the metal wiring layer (206). The surface of the flexible substrate (204) is provided with a groove (208) that is used to thin the flexible substrate (204) in the bending section (203), thereby reducing the elastic modulus of the flexible substrate (204) in the bending section (203) such that a neutral layer in the bending section (203) shifts to the metal wiring layer (206), thus preventing the metal wiring layer (206) from being damaged due to bearing bending stress.
